Has anyone chopped a beach cruiser frame? I'd love to see what you've come up with. I have a good frame from an old cruiser of mine and I want to turn it into something speedy and comfy but not quite sure where to start. Has anyone put speeds on instead of a fixie? Thanks.

Okay now.
Coaster brake does not equal fixed gear.
I'm not sure if you can really chop up a frame to make it more speedy, maybe make it look cool, but really the components would dictate more how fast it can go.

sure you can add gearing to a single speed cruiser, throw on an Internal Geared Hub. I run a shimano nexus 3 speed and its pretty nice...they make a 7 speed as well. Or you can go cheaper and get a Sturmey Archer IGH...

I suppose you could also throw on a freehub with a cassette and spread out the rear forks to make it fit and then drill out some holes for a dérailleur, but that could be difficult to adjust.

On the other end you could also change the crankset and put a triple chainring on the front... front dérailleurs are comparatively easy to put on a bike thats never had em.

i can think of only one thing that would make any cruiser lighter is speed holes in the frame
